  • Publication number: 20240098003
    Abstract: Systems and methods may be used to assess network communications by generating one or more current communication parameters based on communications at an intelligent electronic device (IED) within an electric power delivery system. Network communications may be assessed by determining, at the IED, whether the communications fall within one or more thresholds for the current communication parameters.

  • Patent number: 11569848
    Abstract: The disclosed invention includes methods for linking individual software-defined radios (SDR) into a cohesive network of SDRs capable of recording a sample of radiofrequency (RF) signals emitted in an RF environment. Individual SDRs communicate with an IP network, and host a linking application that executes the recording. A user identifies a lead SDR from among the SDRs, and uses the lead SDR to task participating SDRs with reference to a clock source. Also disclosed is a system of SDRs configured to be linked into a cohesive network of SDRs capable of recording a sample of RF signals emitted in an RF environment. Embodiments of the disclosed invention include co-located and dispersed SDRs. Some embodiments use SDRs organized into a mesh network. Embodiments of the disclosed invention are configured to perform total band monitoring, total band capture, RF environment simulation, interference identification, interference simulation, and distributed quality of service evaluation of wireless networks.

  • Publication number: 20110015943
    Abstract: A system and method for providing health care services, such as medical intake screening and follow-up patient care, including management of medical records and access to patient information for incarcerated individuals. Data regarding medical information collected during an initial intake and screening process and subsequent physical examination may be inputted into a data repository. Triggers based upon the specific data entered may generate alerts for follow up medical care.
